(Cl. 150-3) provide a frame for a suction cleanerfilter bag opening having pivoted first members and pivoted secondmembers and hinge means for movement of the second members into and outof the plane'of the first members to open and close the bag opening. Afurther object is to provide a frame for a filter bag opening and t 1which, when moved toward closed position, has first members bowed awayfrom each other and second members bowed toward each other, and clampingmeans securing the first members together in a straight'line and forcingthe second members together in a straight line closed position. Otherobjects and advantages of the invention will be apparent from thefollowing description and drawings, wherein:

Figure 1 is a side elevation of a suction cleaner embodying the newfilter bag;

Figure 2 is a plan view of the bag opening frame in closed position;

Figure 3 is a side view showing in full lines the position of the framemembers in different planes when in closed position, and in dottedlinesthe position of some of the frame members 'upon movement into the planeof the other members;

Figure 4 is a perspective view showing the bowed arrangement of theframemembers during movement to open and closed positions;

Figure 5 is a top perspecive view of the bag opening frame in openposition; and

Figure 6 is a section along the line 6-6 of Figure 1.

In Figure 1 is disclosed a suction cleaner embodying the improved bag 10and comprises a body 11 including a nozzle 12, a housing 13 for anunshown motorfan unit, and a fan chamber exhaust conduit 14. The cleanerbody is supported on front and rear wheels 15 and 16 respectively, and ahandle 17 is pivotally mounted at 18 to the cleaner body 11. The lowerend of the bag 10 is provided with an inlet 19 detachably secured to theexhaust conduit 14 and the upper end of the bag has a top opening 20which is closed by a resilient U-shaped clamp 21 and the latter issuspended from the handle 17 by a spring 22.

The top opening 20 of the bag is formed by a frame having a pair oflarge members 25 and a pair of smaller members 27. Each of the membersare of resilient material formed to inherently assume the bowed contourshown in Figure 5. The adjacent ends 2'9-29 of the large members 25 arepivotally connected by a hinge 30, the opposite ends 31-31 are securedto the ends 32-32 of the smaller members 27 by hinges 33, and theadjacent ends 34-34 of the small members 27 are pivoted together by ahinge 35.

The construction of the hinges 33 is clearly shown in Figure 3 andcomprises lugs 36 and 37 on the members 25 and 27respectively, and thelugs are arranged at an angle of 45 degrees with these members. Each ofthe lugs 36and 37 is provided with a bore in which is rotatably mounteda pin 38 to pivotally connect the adjacent ends of the members 25 and27. The hinge pins 38 guide the movement of the small members 27 and thehinge for rotation through an angle of 90 degrees relative to themembers 25 as shown in full 21mm ree Patented Nov. 2, 1954 and dottedlines in Figure 3, and the path of movement of hinge 35 is shown by thedot and dash line 39. The hinge 35 has an elongated opening 40 in one ofthe members 27 to provide a loose connection for movement of the hinge35 through the compound angle into and out of the plane of the largemembers 25.

The frame is arranged in a hem 41 at the top of the bag, the largemembers 25 being disposed in a hem portion 42 and the smaller members 27in a hem portion 43. Arranged along the interior of each of the largemembers 25 is a strip of soft material 44 which forms a dust-tight jointwhen the frame members are in closed position.

When the bag opening 20 is closed, the small frame members 27 aredisposed downwardly and inwardly of the bag 10 and normal to the largeframe members 25. The large members 25 are held together in a straightline against their inherent tendency to bow away from each other bysliding the resilient U-shaped clamp 21 on the ends 29 of the members 25throughout the length of the latter to beyond the hinges 33 as shown inFigure 1. The clamp 21 also holds the small members 27 in dust-tightrelation by forcing the ends 32 together against their tendency to moveaway from each ot er.

To open the bag frame, the clamp 21 is slidably removed from the largemembers 25 to release the latter and the small members 27, whereby themembers 27 assume their inherent bowed configuration and move their ends32 about the hinge 35 and the large members 25 about the hinge 30 to theposition shown in Figure 4.

In order to move the frame to its fully open position, the small members27 are pivoted about the inclined hinges 33 to move the members 27 intothe plane of the large members 25. During such movement of the smallmembers 27, the latter also pivots about the single hinge 35 and thebowed direction of the members 27 relative to each other is reversedfrom the bowed position shown in Figure 4 to the contour shown in Figure5.

The dirt is removed from the bag by placing the expanded frame upon apiece of newspaper and elevating the inlet 19, which has been removedfrom the exhaust conduit 14, and shaking the bag whereupon the dirt willfall through the opening 20 onto the paper which is disposed of in anysuitable manner.

To close the bag opening 20 the hinge 35 is moved inwardly of the framecausing the members 27 to move downwardly and inwardly of the bag 10by'pivoting about the inclined hinges 33. During such movement vthebowed direction of the small members 27 is reversed whereby the membersare bowed toward each other. and the hinge 35 holds the adjacent ends 34together. The large members 25 are then moved toward each other topermit the clamp 21 to be telescoped about the ends 29, and thereafterthe clamp is moved alon the large members to also enclose the hinges 33.When the clamp 21 has completely telescoped the large members 25, thelatter are held together in a straight line and the soft material 44 iscompressed to form an air tight seal. The clamp 21 also holds the smallmembers back to back in a straight line to form an air tight seal, thehinge 35 securing the ends 34 of the members 27 and the clamp 21securing the opposite ends 32 against their inherent tendency to bowaway from each other.

While I have shown and described but one embodiment of my invention, itis to be understood that that embodiment is to be taken as illustrativeonly and not in a limiting sense. I do not wish to be limited to theparticular structure shown and described but to include all equivalentvariations thereof except as limited by the scope of the claims.
